We really like what we’ve seen from (Joe) Wieland this spring. He was really good in San Antonio the other day,” Zaidi said Sunday. “(Carlos) Frias and (Mike) Bolsinger are guys that all along we felt comfortable with. You also want to create a situation where the guys you have internally who have been told they have a chance to compete – you want to give them the opportunity first if it arises.”

Joe Wieland most recently pitched against the Texas Rangers in San Antonio during Big League Weekend, giving up three hits in 3.0 innings, issuing two walks and striking out four. So far this spring, he has thrown a total of 9.0 innings, has nine strikeouts and a 1.00 ERA.

The right-hander was a September callup for the San Diego Padres last season and earned his first career win on Sept. 24 against the Colorado Rockies. Wieland is a career 1-4 with a 5.31 ERA in nine game appearances (seven starts) during parts of the 2012 and 2014 seasons.
